Medical Device Classification EU MDR

Determination of the Medical Device Classification and the corresponding classification rule is the first step in the EU CE Marking process. Based on the class and the rule of the device, the technical file and the Notified Body application can be filed.


According to the EU MDR 2017/745, Article 51, medical devices are classified into I, IIa, IIb, and III, considering their intended purposes and their inherent risks. The risk is incremental from class I to class III.
